Application filed-Tune 3, 1918, Serial Nol237,988.

To alldchom it may concern l Be it known that I, GAETANO GENTILE, a

subject 01 the King of Italy, and aresident of the city of New York, borough ofManhattan, in the. county and state of New dork, have myented a new and Improved Macaroni-Drying Plant, or which the fol' lowing is a 'full, clear, and exact description. Among the principal ObJGCtS which the present invention has in view ar'ez'To pro- VldG means for maintaining a continuous 'circulation ofdry air in the presence of suspended macaroni; to provide means for at 'will reversing the direction of the blow of air utilized for drying the product; to pro- Q vide means for removing the heavier or j ranged in vention;

humid air, and to reduce the time required tor drying themacaroni.

As seen in the drawings, a dryingchamher is disposed between the four walls or.

a room, the side walls of the drying chamber being' separated from the sidewalls of the room to form lateral'passages 9. The side wallsof the drying chamber are formed in the major partby doors 10, which have I tween the racks 12 therein.

hinges ll'on which the doors throw outward to permit access to the interior of the dryingchamber and to the passageway be- The rackslQ preferably consist of angle irons arranged to support a woodfillet 13., the upper edge I whereof is fluted to form closely disposed pockets 14'. The pockets 14 'are'provided to receive andhold the ends of the rack sticks 15 on which macaroni 16 is strungor disposed for drying. The racks 12 are superposed and as large a number of racks is used as consistent with the heightof the V drying chamber.

1 to permit free access and exit of the air The drying chamber, 7 of the drawings, is open at the opposite ends shown 'in Fig. 1

taken from anddeliveredto the passages9. The air so deliveredis drawn into the chamber eat one end'and delivered therethrough to the pmpositeen'dby a fan 17 of the reversible type. The fan 171's disposedin a circular passage lS formed in the wall or partition 1'9, which divides the two sectionsof the drying chamber. The fan is supportedin hearings on a'fpedestal 20, and is driven byian electric motor '21 of the reversible type.- The pedestal 20 and the motor 21 are preferably mounted in a space or crevice 22 formed in the partition 19, as. shownbest in Fig. 2 of the dr. Wings, c

The width of the patition 19 is less'than the width of the end portions of the, drying chamber. The side walls of the chamber are shaped to correspond with the divergent widths, and, in consequence, impart .to the chamber in plan a waisted or throated central portion wherein are disposed heat-radiating coils 23, for either hot water or steam. The coils 23 aredisposed between the fan 17and the first tierof macaroni, or racks 12 containing th'e saine. As' eachradiating coil delivers-its heat,"said' heat passes in a. column in front of and to therear ofthe fan 17 to be thereby forcedflforward' into the chamber wherein}themacaroni' is being dried, and drawn through the opposite chamber. The heating arrangement for the drying plant isffurther augmented by sup- 'f plementary heaters. 24, opposite both ends of 'thefdrying chamber, the columnsof the heated air rising from these auXiliar coils being ultimately drawn: in the cham er by I the fan 17.

During the drying of the macaroni and as the result ofthe extraction of moisture therefrom, the alr contained in the chamber becomes impregnated w th molsture and the heavier portion naturally precipitates or falls to the floor of the drying chamber.

It is to remove this heavier air that there 1s provided an auxillary fan 25, which, as shown 1n the draw1ngs,.'1s disposed at the floor of the. outer or containing chamber. The fan 25' serves to carry off the mo1st air above referred to. v H It will be understood that any source of power may be employed todrive the fans 17 r and 25.

' Operation.

Vvhen equipped as shownin the drawings,

and as above described, a drying plantmay i be operated as follows: Macaroni 16 is suspended on the sticks 15, and is then carried by hand within the drying chamber, entering through the doors 10, to be disposed at the far side of said chamber on the racks 12, and within the pockets 14 of the fillet 13.

l/Vhen the chamber has become thoroughly charged, the fan 17 is started, and the air contained in said chamber is circulated, being drawn into the chamber from the surrounding room and from the passages 9 thereof over the coil 24 at one end of the drying chamber to be ejected from the other end ofthe drying chamber above the heaters Zthere located. The circulation is maintained for a given period, when the fan 17 and electric motor operating the same are reversed, and the circulation then inaugurated and maintained in the reverse direction. This alternation of circulation is proceeded in until the macaroni containedin the chamber i found to be dry.

During this entire operation, a fan 25 is continuouslyblowing from the passages 9 the moisture-laden or humid air.

It will be found that whenemploying an apparatus such as described, a given amount of macaroni maybe dried in about fifty per cent. otthe time required when en'iploying the conventional methods. V
